Providers can ensure video quality by applying algorithmic compression techniques such as chroma subsampling , which uses color variation undetectable to the human eye 供應(yīng)商通過應(yīng)用諸如色彩子取樣等算法壓縮技術(shù)確保視頻的質(zhì)量,所謂的色彩子取樣使用了人眼觀察不到的顏色變化。
百科解釋
Chroma subsampling is the practice of encoding images by implementing less resolution for chroma information than for luma information, taking advantage of the human visual system's lower acuity for color differences than for luminance.
